Control Effect Evaluation of Nine Kinds of Fungicide Combinations Against Potato Late Blight
摘要
Abstract
In order to prevent potato late blight with high efficiency and low residue ,field experiments for nine kinds of fungicide combinations against potato late blight were conducted .The results showed that the control effect of the treatment B[80% Ethylicin EC+80% Mancozeb WP+ (80% Ethylicin EC+80% Mancozeb WP mixture)] against potato late blight was the best ,followed by the treatment C [80% Ethylicin EC+80% Man‐cozeb WP+ (80% Ethylicin EC+50% Carbendazim WP mixture)] and the treatment K[58% Maganese Zinc WP +58% Maganese Zinc WP+58% Maganese Zinc WP] .The control effects were 81 .54% ,74 .66% and 71 .27% respectively .The yield of B was the highest ,31 303 .95 kg · hm‐2 ,followed by C and K , 24 363 .60 kg·hm‐2 ,23 525 .25 kg·hm‐2 .At 1% level ,there was significant difference between B and CK .Pota‐to late blight should be prevented more than thrice where the disease often occurred .In the early part of the disease ,protective agent was used ,and in the late part of the disease ,therapeutic agent was used ,the effect of which was more ideal .关键词
